The Ravens placed three players on injured reserve, officially ending their seasons.

That includes defensive ends Brent Urban (torn anterior cruciate ligament) and Kapron Lewis-Moore (rupture Achilles), who have both undergone surgeries already, and offensive guard Will Rackley. Rackley sustained a concussion during the first week of training camp and had a history of concussions with his previous NFL team, the Jacksonville Jaguars.

** Brown had lost ground on the depth chart with the addition of newcomers Terrence Brooks and Darian Stewart as well as the special-teams ability of Anthony Levine and Brynden Trawick.

** Wiliams is a Poly graduate who was cut last year after playing on the Ravens' Super Bowl championship team. The former Maryland standout wasn't getting much playing time and faced long odds with such a deep receiving corps that includes Steve Smith, Torrey Smith, Jacoby Jones, Marlon Brown, Michael Campanaro, Deonte Thompson and Kamar Aiken.

** The veteran Spitler faced long odds to make the final roster due to the presence of Daryl Smith, C.J. Mosley, Arthur Brown, Josh Bynes and Albert McClellan.

Spitler was running third on the depth chart behind Bynes at middle linebacker. He was signed by the Ravens after a tryout at a June minicamp.

A 2010 seventh-round pick of the Miami Dolphins, the 6-foot-2, 250-pound former Ohio State standout tied for third on the Dolphins last season with eight special-teams tackles.

For his career, Spitler has 28 special-teams tackles and one fumble recovery in 55 career games.

** Mims -- a 6-foot-8, 350-pound lineman from Virginia Union -- was signed to a reserve-future deal by the Ravens last year and spent time on their practice squad last season.

He had a previous stint with the Kansas City Chiefs' practice squad.

Mims was one of the few healthy players who didn't play against the Washington Redskins on Saturday night.

** DiMarco, a rookie outside linebacker, had a previous stint with the New York Jets.

He was signed after a June minicamp tryout.

DiMarco played at William Penn University -- an NAIA school in Oskaloosa, Iowa. The 6-foot-2, 237-pound native of St. Charles, Mo., was a third-team NAIA All-American selection last season. He had a school-record 13 sacks last season along with 55 tackles, 26 for losses, three forced fumbles, two fumble recoveries and three blocked kicks.

DiMarco played defensive end at William Penn, converting to outside linebacker in the Ravens' 3-4 scheme.

DiMarco recorded one sack in the Ravens' first preseason game against the San Francisco 49ers.

** Leone, a left-footed punter from the University of Houston, had a 40-yard punt against the Dallas Cowboys.

Leone has a strong leg, but faced long odds with veteran punter Sam Koch entrenched for the past several seasons.

** Norman is a former Coastal Carolina standout who was signed after playing in the Arena Football League with the Cleveland Gladiators.

Before being signed by the Ravens, Norman had a dozen interceptions to rank second in the league and was the Gladiators' second-leading tackler. Last year, Norman had seven interceptions for the Gladiators.

** Wood is a former Notre Dame player who was signed to a reserve-future deal after last season.

Wood was last with the New England Patriots on their practice squad, but didn't stick with New England and was released Dec. 26 after being signed Nov. 5.

Wood rushed for nine yards on three carries in three games with the Texans last season.

After serving a two-game suspension as a senior for violating team rules, Wood rushed for 742 yards and four touchdowns. As a junior, he rushed for 1,102 yards and nine touchdowns and caught 27 passes for 187 yards.

* * Van Sloten is an undrafted rookie from Iowa regarded as a developmental prospect. His knee injury was serious enough that it would have sidelined him for at least a few weeks.
